I'm taking Pre-Calculus I here at my community college. From there, students can go to either Pre-Calculus II or Applied Calculus (but not to "regular" Calculus I). Applied calc. is supposed to be business calculus used in business, biology, and other degrees and the director told me that they don't use trig. functions at all, so Pre-Calculus II (where those topics are taught) is not a pre-requisite. Some questions: 1.) I am going to take Pre-Calculus II anyways at a bare minimum, because I eventually want to take Calculus I (and you need it for that). But, I'm soooooo intrigued with being able to do some calculus right away that I'm tempted to take Applied Calculus concurrently with my Pre-Calc. II next semester. Does anyone see any math difficulties that might arise if I did this? Would simply taking Pre-Calc. II first help in some way before taking Applied Calc. I know the director said you don't need PCII, but I'm wondering if there's anything else I might be missing here? Like any dangers to doing this? I just don't want to take AC and find I'm not able to handle it or it's way too hard. Would something like AC be considered a very hard class? I know that's relative question, but my background is that I'm a hard worker and have gotten all A's in my math classes thus far. I am not a natural at the subject, but very curious about it and enjoy it nonetheless. I am willing to work hard at it. 2.) Would taking Applied Calc. first help with or possibly even (the opposite) mess up anything I do in Calculus I later on? How are they related and different? Would they complement each other nicely? Would there by any confusion, advantages, disadvantages, etc. in taking one first vs. the other? My plan would be to do this: Spring 2015: Pre-Calc. II and Applied Calc. Fall 2015: Calc. I Feedback?
